Upgrade your locked Cingular GSM Treo 650

We reported on the recent Treo 650 ROM update for unlocked GSM devices a couple of days ago. Cingular and palmOne have not yet issued this latest update for Cingular-branded devices and some people would like to update them. Cody Walker over at TreoCentral posted a detailed guide on upgrading a locked Cingular Treo 650. This upgrade procedure can also be useful for removing all the Cingular-installed utilities and programs. Make sure you read and follow the procedure exactly so you don't end up bricking your smartphone. Thanks to XistBoi for the link.

Aim for your big toe when u do this(11:35am EST Mon Jun 20 2005)The problem with following a method like this is that you will lock yourself out of receiving the real Cingular updater later on. You cannot go sideways or backwards from these bogus ROM update methods. – by Footshot

facts about treo 650 unlocking(6:51pm EST Sun Jul 03 2005)You cant kill your treo 650 by unlocking it. Only when you firmware it incorrectly can you take your chances. . Thats the true fact.between the two people 4321media and mobile2mobile both were very helpfull in the process. Unlocking doesnt kill your treo 650 in any way or modify it. Only if you run the firmware update wrong does it kill your treo. – by geeksforyou

Where to get a Treo 650(10:45am EST Mon Jul 04 2005)Best advice on where to get an unlocked Treo 650 or a locked one and get it unlocked safely.

I have T-Mobile, they support Treo 650 and I want to stay with them. But they do not offer any deals on Treo 650 in fact they don't offer it at all at any price. My Nokia just died and I don't want to get anything but a Treo 650.

Any help or advise?– by Molly

I did it ! – Treo Unlocking For Beginers(1:43pm EST Thu Nov 17 2005)I was researching this stuff for 2 days I decided to go with they have 2 buttons you should see one is called sunsets and it tells all the things NOT TO DO it is a case history of customers like my self who had a less than perfect flight. MY MISTAKE WAS TRYING TO DO IT ON WINDOWS ME. MY OTHER MISTAKE WAS NOT BEING PATIENT and almost unplugging my phone during the palm rom upgrade process. ALSO be sure to unplug all unneeded usb things because they might conflict with your Treo during this process THE OTHER BUTTON at fasttutorials.com is called CHECKS if you click on that the give you a 10 step check list to make sure everything is in order before you hit the EXECUTE button. I would say if you read both of those buttons and FOLLOW THE INSTRUCTIONS but most of all be patient your phone should be unlocked in about an hour, the actual unlocking process takes about 30 seconds BUT DON'T LET THAT FOOL YOU that only makes you expect more than what your gona get, the time it takes to read the palm os update instructions and then do the palms os update, and then read the unlock instructions, read them again and then perform the unlock takes about an hour so don't go getting all upset like I did and giving the fasttutorials.com chat lady a hard time. I said some mean stuff and she almost told me where to go with my self, but instead I recovered and fortunately my chat with her got cut off before I could ask for a refund AGAIN MY MISTAKE WAS THINKING IT COULD ALL BE DONE IN 5 MINUTES like most the web sites advertise. I would say that if you have done it before and the Treo is already running the latest OS then easily you could do it inside of two minutes HOW TO SPEED THINGS UP. After you make your payment email those guys and let them know. also send to them in there email your paypal RECEIPT ID you will get that automatically when you make your payment but you will need to WRITE IT DOWN for your records. So best case scenario if you did this before a couple of minutes IF YOUR A BEGINNER AND THIS IS YOUR FIRST TIME your best friend on this run is PATIENCE, it will take you an hour cause you gota take a do-it-you – by Tristan Giallani

Treo unlock(10:54pm EST Sun Nov 20 2005)I completed the unlock within a few minutes using I guess as long as your computer is free of Windows issues, it will be a breeze. – by Gina

Treo unlock(3:11pm EST Tue Feb 14 2006)I was very hesitant and suspicious of paying someone for an unlock code but broke down and went to

It seemed complicated but was really very easy and it worked great. – by Jeff in Atlanta

Treo Unlock(10:51am EST Wed Mar 08 2006)DO NOT USE Milton is the guy who is going to charge you. I paid and had to wait hours before I even received an email with 4 lines worth of instructions. After viewing the FASt Tutorial, I realize that I was never instructed to put the phone in boot loader mode. This guy is an idiot, can barley communicate in english and will use fould language with you if you file a paypal complaint. His solution to me was first for me to install MSN messenger so he can take control of my computer…….I Think Not!, his second solution was to wait 2 days while he writes a C++ program…..Again….I think not. Also, all of these companies are all using the same exact GSM server and software, and seem to be of ASIAN origin. By connecting to these servers, you are giving them your IMEA number, which is all thats necessary for them to make phones which will bill your account. Additionally in order to perform the unlock step, you must expose your computer through your firewall to an unkown entity on the internet communicating with some unknown software on your computer…..Might as well just give them all your passwords. Just call your carrier and tell them that you will be traveling abroad, and intend to use pre-paid SIM cards. They will issue you an unlock code. – by Ernie

Brilliant unlock!(4:09pm EST Thu Mar 09 2006)You do not have to provide IMEI to unlock. The instructions at (fasttutorial without the 's') is good. As a dealer I have unlocked 750 phones with them to date, both treo 600 and 650. – by dealerclub

HELP(6:42pm EST Sat Mar 18 2006) i have a treo 650 that i got in mexico , i dont have either the USB cable or the money to buy one of those unlock codes… is there a simple/free way to unlock it ?? – by paco

Unlock Your Cingular Treo 650(11:13am EST Sat Jun 24 2006)Cingular will give you the unlock code for free as long as you are a customer in good standing.

Call and tell them you got a new phone and want to give this one to someone who isn't with Cingular. They will give you an eight digit unlock code.

With a Cingular SIM card in the phone (doesn't have to be an active SIM card) just turn on the phone and dial *#*#code# and hit send. You will get a message that the phone is unlocked.

Insert your other carrier's SIM card and away you go.

Just did it today and it worked for me. Hardest part was finding someone who had an old Cingular SIM card.

Thank goodness I tried again at Cingular before I paid the local cell repair place $75. – by TryingToBeHelpful
